YAG focusing lenses available in focal length from 20 to 150mm. The lenses are anti-reflection coated with a high damage narrowband multilayer AR coating @ 1064 nm.
YAG lenses are color corrected, a HeNe guide beam or visible range video monitor beam will be in focus at the same position as the YAG beam.
For high power laser applications, optional protective windows attach to the focusing side of the lens.
